avcodec/vp3: Add missing check for av_malloc
Since the av_malloc() may fail and return NULL pointer,
it is needed that the 's->edge_emu_buffer' should be checked
whether the new allocation is success.

Alternative fixes would be allocating a few bytes more at the end instead of a whole
line extra or to adjust the threshold where the edge emu code is activated

The CQ calculation gets thrown off and behaves very nonsensical
if it isn't set to 0.

a1f13b592b swscale: aarch64: Fix yuv2rgb with negative strides
Treat the 32 bit stride registers as signed.

Alternatively, we could make the stride arguments ptrdiff_t instead
of int, and changing all of the assembly to operate on these
registers with their full 64 bit width, but that's a much larger
and more intrusive change (and risks missing some operation, which
would clamp the intermediates to 32 bit still).

configure: link to libatomic when it's present
C11 atomics in some configurations (e.g. 64bit operations on ppc64 with
GCC) require linking to libatomic.

Fixes #9275
